The overclocking champion returns.
Last year I looked at MSI’s N480GTX Lightning card which was one of the most overclockable GTX 480 in the market. As such, the N580GTX Lightning had big shoes to fill, and I was wondering if it could exceed my expectations.
Starting things off, let’s look at this giant. The MSI N580GTX Lightning has a huge Twin Frozr III heatsink on top, complimented by two 9CM PWM fans which run at 1k rpm, jumping to 1.4k during load. This whole design was not only to keep the GTX 580 extremely cool, but much quieter than the reference GTX 580 fan.
The entire heatsink is one single block, covering the entire card, and the two 8mm pipes helping distribute heat evenly. Obviously all of this leads to the N580GTX Lightning’s 30.5cm length, so make sure your case can support it!
Of course, the N580GTX Lightning doesn’t just have the Twin Frozr III to thank for its cool and quiet operations; much of the design process was also focused on power delivery with the help of 16-phase power connectors, 12 of which are dedicated to the GPU, double that of reference cards. This increase in current is also accompanied with an 8+8 pin power connector as opposed to the 8+6 pin reference design. Speaking of which, the minimum power supply requirements for the N580GTX Lightning is a 700W PSU.
